Alexandre Brongniart

Alexandre Brongniart , 1770-1847, French geologist, mineralogist, and chemist. As director of the Sèvres porcelain factory from 1800, he was responsible for its international fame. He was professor of mineralogy at the Museum of Natural History in Paris from 1822-47. Brongniart established basic principles of ceramic chemistry in his Traité des arts céramiques et des poteries (1844). With George Cuvier he wrote Essai sur la geographie mineralogique des environs de Paris (1811), in which a system of stratigraphy was developed that relied on the use of fossils for the precise dating of strata. He was also the first to develop a systematic study of trilobites and a system for the classification of reptiles.

Brongniart, Alexandre (1770–1847) Brongniart was professor of mineralogy in the Paris Museum of Natural History, and collaborated with Cuvier in his work on the mapping of the Paris basin. He demonstrated that lower taxonomic orders of animals were found lower in the stratigraphic column, claiming this gave evidence of progression in the succession of life.
